Abstract
The present paper approaches heat transfer in a class of cancer treatment which uses heat to kill cells affected by the disease. The theme has been chosen based on the great importance of this type of treatment as a tool to fight cancer. This research focuses on Photo Thermal Therapy (PPT), in which the source of heat is a laser beam. Whenever a laser beam is applied to irradiate a diseased region of a tissue, there is no way of avoiding radiation being absorbed by the surrounding healthy region. However, there are ways to partially control the temperature distribution during PTT in order to mitigate the side effects of the treatment and to avoid patient suffering. In this context, heat transfer simulations can be very useful, since they provide knowledge which can lead to procedures for a better control of temperature. In this research a two-dimensional computer code written in FORTRAN90 was devised to find the divergence of the radiative heat flux, which is provided by a Monte Carlo (MC) code. The main objective of this development is to provide a tool which can be used to investigate how the use of nanoparticles can affect the divergence of the radiative heat flux and temperature distribution in living tissues during PTT therapies
